Usually, filter order matters only a little with good-quality filters, but there are a few practical rules:

• Put the better multi-coated, less reflective filter closest to the lens. This can slightly reduce internal reflections, because reflections between stacked filters are more likely when a more reflective filter sits in the middle of the stack.
• If one filter has a smaller diameter, place it closer to the lens to help reduce vignetting.
• A circular polarizer is typically best on the outside/front of the stack.

For an ND and an 80A color-correction filter, the order generally won’t make a noticeable difference if both are decent filters. Any visible difference you see by holding them up to a light is likely to be very small in actual photographs.

So the general answer is: yes, order can matter, but mostly for minimizing reflections, avoiding vignetting, and accommodating special filters like polarizers—not because the filter effects themselves fundamentally change when swapped.
